Northern Ireland Coastal Bedrock Geology Map

Northern Ireland's coastal bedrock geology is detailed in this dataset, created by the Geological Survey of Northern Ireland (GSNI). It refines the 1:10,000 digital bedrock map to cover a 200-meter inland buffer and extends seaward to approximately 10 meters depth, aligning with the Northern Ireland 3-Dimensional Coastal Survey. Unpublished data was incorporated to fill gaps in the original mapping.

Use Cases

• Coastal erosion modeling based on bedrock type and structure.
• Marine habitat assessment linked to underlying geological formations.
• Planning coastal infrastructure projects using detailed bedrock maps.
• Refining regional geological models with updated coastal data.

Strengths

• Derived from authoritative 1:10,000 scale digital bedrock geology maps.
• Spatially aligned with the comprehensive Northern Ireland 3-Dimensional Coastal Survey.
• Refined to account for significant coastal changes since the original survey.

Limitations

• Column names and data structure are unknown, limiting immediate usability.
• Metadata for row count, file size, and author is incomplete or missing across platforms.
